How to shut down the swoole daemon

1. Use SWOOLE in the project today, accidentally open the guardian process in the configuration (that is, the process is running in the background) (Recommended learning: # swoole video tutorial)

##2. When debugging the socket code, the process ended and was restarted, and it always showed that the port was occupied

3. Even if the terminal command running window is closed and reopened at this time, the port is still occupied and the process cannot be started again. The solution is as follows:

The first step is to change the daemon process in the code to 0

The second step : Find the pid of this port number (the port my code listens to is 9503), and get the PID

The command is as follows:

netstat -apn | grep 9503

Step 3: Kill the process

The command is as follows:

kill -9 186691

At this time, you can restart the listening program. No more error reports that the port is occupied
